Given numbers are 780,939,311,807,243

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 780,939,311,807,243 is 1654385169060.

Find LCM of 780,939,311,807,243 with Prime Factorization

Multiply the prime numbers at the bottom and the left side.

3 x 260 x 313 x 311 x 269 x 81 = 1654385169060

Therefore, the lowest common multiple of 780,939,311,807,243 is 1654385169060.

LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

Firstly, we have to find the product of all the numbers.

780 x 939 x 311 x 807 x 243 = 44668399564620

Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.

780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780

939 : 1, 3, 313, 939

311 : 1, 311

807 : 1, 3, 269, 807

243 : 1, 3, 9, 27, 81, 243

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 780,939,311,807,243, is 1.

Now, the common factors can be found like this.

780:2x 2x 3x 5x 13

939:3x 313

311:311

807:3x 269

243:3x 3x 3x 3x 3

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

3x 3x 3 = 27

Therefore, the value for common factors is 27.

Now that we have all the elements of the formula, we can plug them in to calculate the LCM.

LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

LCM = 44668399564620/(1x27)

LCM = 44668399564620/27

LCM = 1654385169060

Thus, we can understand that the LCM of 780,939,311,807,243 is 1654385169060.
